CIGARETTE-TUBE.

SPECIFICATION forming part of Letters Patent No. 716,536, dated, D mber 23, 1902.

Application filed May 14 1902.

Serial No. 107,333. (No model.)

To all whom it may concern:

Be it known that I, KARL HARNISOH, a citizen of the Swiss Republic, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in Cigarette-Tubes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

In a certain class of cigarettes the tobacco is contained in a thin paper tube, this tube having inserted in that end which is to be placed in the mouth a mouthpiece which is usually formed of rolled flexible materialas, for instance, a rolled paper blank. In making the better cigarettes of this class it is customary to use some means for preventing the tobacco from passing backward into the mouthpiece.

The object of this invention is to produce a cigarette-tube provided with simple, inexpensive, and efficient means for preventing the tobacco from passing into the mouthpiece.

With this object in View the invention consists in a certain construction to be hereinafter described, and fully pointed out in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same parts, Figure 1 is an elevation, partly broken away, of the improved form of cigarette-tube. Fig. 2 is a plan view of the blank from which the mouthpiece of the cigarette is formed.

Referring to the drawings, 175 indicates a paper tube which forms a shell in which the tobacco is contained. This tube has inserted in one of its ends a mouthpiece 176, said mouthpiece being preferably formed from a rolled-up blank. In the cigarette illustrated the mouthpiece lies entirely within the tube, so that the tube serves to hold the coils of the rolled blank in position and to retain it in place; but the construction may be varied in this respect, if desired.

Lying behind the tobacco-containing chamber of the tube in position to prevent the tobacco from passing into the mouthpiece is a series of pointed tongues 177. While these tongues may be formed in any desired manner, they are preferably integral with the mouthpiece and are formed by a series of angularly or diagonally arranged slits 178, as clearly shown in Fig. 2.

In forming the mouthpiece the pointed tongues are first bent at a substantially right angle to the body of the blank, and the blank is then rolled up. When the blank has been thus rolled, the tongues project inward and their apices form a substantially circular orifice through which the smoke of the ignited cigarette may be drawn into the mouthpiece, but which is not sufliciently large to permit the tobacco to pass into the mouthpiece-chamber. The slits or incisions which form the pointed tongues are preferably of sufficient width, so that when the mouthpiece-blank is rolled up the edges of the tongues do not overlap. In fact, it will usually be advantageous to make the slits of sufficient width so that the edges of the tongues are slightly spaced apart when they are in position in the rolled blank.

The slits by which the tongues are formed can be readily cut during the manufacture of the mouthpiece by machinery and form an exceedingly cheap and efiicient means for preventing the tobacco from passing into the mouthpiece-chamber. Slight variations may be made in the construction without departing from the invention.

What is claimed is l. A cigarette-tube provided with a mouthpiece and having located in the interior thereof a series of inwardly-projecting pointed tongues arranged to prevent the tobacco from passing into the mouthpiece.

2. A cigarette-tube provided with a mouthpiece and having located in the interior thereof a series of inwardly-projecting pointed tongues, the edges of which are spaced apart and the apices of which form a substantially circular orifice, said tongues being arranged to prevent the tobacco from passing into the mouthpiece.

3. A cigarette-tube comprising a tobaccoholding shell and mouthpiece, said mouthpiece being formed of a rolled blank provided with a series of integral inwardly-extending pointed tongues, the apices of which form a substantially circular orifice.

4. A cigarette-tube comprising a tobaccoholding shell and a mouthpiece, said mouthpiece being formed of a rolled blankwvhich In testimony whereof I have hereunto set has a part of one of its edges slitted to promy hand in the presence of two subscribing I0 vide a series of inwardly-extending pointed Witnesses.

ton ues the slits being of sufficient width so i 5 that the edges of the tbngues do not overlap KARL HARNISOH' When the blank is rolled and the tongues bel/Vitnessesz ing of such length that their apices form a JAMES Q. RICE,
